IV.阅读理解
Can yu imagine a wrld withut music? Studies shw that public schls acrss the cuntry are cutting back n music classes t save mney. Wrse, sme schls have never had music classes t begin with. But withut them, students' academic grwth and emtinal health culd suffer. In fact, music classes are necessary fr all students in schls.
Recent studies by Brwn University have shwn that students wh received music educatin classes were better in math and reading skills than thse withut music classes. Anther study by The Cllege Bard fund that students taking music and art classes gt higher pints. Students' academic success seems t depend n their taking part in music educatin.
Music prgrams in public schls als help t add t a student's sense f pride and self－cnfidence. Teens tday have t many learning tasks. Besides, they have family prblems, self－cnfidence prblems, relatinship trubles, and chices abut drugs and alchl. All f these can stp academic success, but music educatin can help. A study by The Texas Cmmissin n Drug and Alchl Abuse fund that students wh tk part in schl music prgrams were less likely t turn t drugs. Music prgrams encurage students t wrk tgether t prduce an excellent perfrmance.

Althugh they culd nt cmmunicate verbally (口头上), they were able t read the music in rder t play the duet. Tw students frm different cultures wrked as a team with self－cnfidence and cmmn purpse thrugh music.
The gift f music is priceless. We need t be sure t have necessary music classes fr all students. The wrld is lsing its music, and putting music int schls is the first step t get it back.
32. Educatin with music classes culd ________.
A. waste a lt mre mney frm parents

【答案】32. B 33. C 34. C 35. D
【解析】这是一篇说明文。主要介绍了音乐课对学校里所有的学生的重要性。
【32题详解】
细节理解题。根据第二段Recent studies by Brwn University have shwn that students wh received music educatin classes were better in math and reading skills than thse withut music classes.可知，布朗大学最近的研究表明，接受过音乐教育的学生在数学和阅读能力上比没有上过音乐课程的学生要好。由此可知，音乐课可以帮助学生提高他们的学习成绩。故选B。
【33题详解】
细节理解题。根据第二段整体内容尤其是最后一句“Students' academic success seems t depend n their taking part in music educatin.”可知，音乐在学生的成功中扮演着重要的角色。故选C。
【34题详解】
细节理解题。根据第四段第一句“Music crsses language, class, cultural and plitical bundaries (界限)．”可知，音乐能够跨越语言、阶级、文化和政治界限，使人们做到无国界沟通交流。故选C。
【35题详解】
主旨大意题。根据第一段最后一句“In fact, music classes are necessary fr all students in schls.”事实上，音乐课对学校里的所有学生都是必要的。和最后一段最后一句“The wrld is lsing its music, and putting music int schls is the first step t get it back.”这个世界正在失去它的音乐，把音乐引入学校是找回它的第一步。所以短文的最佳标题为“学校中的音乐教育”。故选D。
【36题详解】
考查段中句。根据空前“But first, yu shuld make sure if yu're experiencing sme serius illnesses.(首先，你应该确定你是否患有一些严重的疾病。)”和空后“keep these tips in mind.(记住这些提示。)”可知，F项(如果你身体健康但需要额外的能量)能够承接上文并且与下文连接通顺。故选F项。
【37题详解】
考查段中句。根据空前“The secnd thing t wrk n is t g t sleep early enugh t get a full night's sleep, preferably s that yu wake up naturally withut the need fr yur alarm.(第二件事要做的是早点睡觉，这样可以睡一整晚，早晨最好自然醒来而不需要闹钟。)”和空后“Thus, anther useful tip is t take a nap during the afternn.(因此，另一个有用的建议是在下午小睡一会儿。)”可知，D项(然而，这一目标在实践中很难实现)能够承接上文并且与下文连接通顺。选项中的this gal指的是前一句中的“早晨不需要闹钟自然醒。”故选D项。
【38题详解】
考查段尾句。根据空前“The best length f time fr a nap is abut 20 minutes. Shrter, and yu wn't get much ut f it.(再短一点，你就没什么收获了)”可知，E项(再长一点，你可能会发现晚上很难入睡)能够承接上文。选项与前一句的句式结构是相同的。故选E项。
【39题详解】
考查段首句。根据空后“Drinking plenty f water and fluids thrughut the day is ne imprtant way t stay energized, since dehydratin leaves us in lw sprits.(每天多喝水等液体饮品是保持活力的一个重要途径，因为脱水会让我们情绪低落。)”可知，G项(其他增加活力的方法包括我们的饮食和饭食)能够与下文连接通顺。后文的water和meals是对选项的具体举例。故选G项。
【40题详解】
考查段尾句。根据空前“Be aware als that peple wh are verweight are mre likely t experience tiredness easily.(还要注意，体重超重的人更容易感到疲劳。)”可知，选择A项后整个句子意为“如果你超重，减少额外的体重可以帮助你获得更多的精力。能够承接上文。选项中的verweight与逗号后的extra weight是同义表达。故选A项。
